I This said intermediate gear-wheel or ing-engine having my improvements. The pulley 17 in turn meshes with a large gear- 5 steam-producing or other motive devices and wheel or pulley 19, keyed or otherwise fixed the immediate connections therewith for upon the shaft 11. Thus rotary motion and transmitting power are not shown, being of power are transmitted from the source of t any ordinary construction. Fig. 2 is a side power to said shaft 11, which latter is caused elevation of the parts shown in Fig. 1. Fig. to operate continuously in one direction of 9 3 is a section taken through line 00 of Fig. 1, rotation. The said toothed gearwheel19,fixed and Fig. 4: is a section taken through liney to the shaft 11, is on its inner side provided 1 of the same figure, Figs. 3 and 4 being on an with a friction-cone 20, adapted to engage 45 enlarged scale and showing clearly the more the flange 21 of a section 121 of the slida'ble important novel features of the invention. mast-rope drum 12, the said flange 21 being Fig. 5 is a section taken through line 2 of Fig. hollowed at its outer side, or side'toward the 4. Fig. 6 is an enlarged detail elevation, wheel 19, and having the walls of its chamber tact with the said cone 20. Thus when the drum 12 is moved longitudinally on the shaft 11 toward or into contact with the cone 20 the said drum will rotate with the wheel 19, as will be obvious.

The drum-section 121 is moved longitudinally on said shaft 11 by means of connected levers 22, arranged at opposite sides of the frame 10, in connection with screw-threaded shafts 23 231 in brackets 24 241, fastened to the bed or frame 10, by means of bolts 25, at points on said frame adjacent to the extremities of the shaft 11, the said brackets extending' in alinement with said shaft 11 considerably beyond said shaft 11 and in alinement with the axis of the said shaft 11, providing threaded perforations in which the screw-shafts 23 and'231 have their bearings. The two screwshafts disposed beyond the opposite ends of the shaft 11 and in axial alinement with said shaft 11 are threaded alike and when they are moved together by means of the connected compound levers one follows the other, one screw-shaft moving toward the shaft 11, while the other moves away therefrom, and the movements being of uniform extent.

The opposite ends of the shaft 11 are bored out at the longitudinal axes thereof, and within the borings are arranged longitudinallyslidable key-shafts 26 261, which extend from transverse slots through said shaft 11 outwardsa little beyond the extremities of said shaft 11 into contact with the inner ends of the screw-shafts 23 231, the shafts 26 261 fitting neatly the axial chambers prepared therefor, so as to secure a smooth and positive sliding movement.

At the inner ends of the sliding shafts 26 261 V the same engage the transverse keys 27 271 in the transverse slots above referred to. Said keys have a limited sliding movement lengthwise of the shaft 11, and, extending laterally through said slots from the shaft, they enter slots 30, Fig. 5, of pressure-plates 31 311, arranged loosely around the shaft 11 at the opposite extremities of the body of the mast-rope-drum sections 121 122, the latter being preferably chambered or recessed, as at 32, to receive said pressure-plates 31 311 and preferably intermediate friction plates or washers 45, of hardened steel, by means of which increased durability is gained.

At or near the end of the shaft 11 opposite that having the gear-wheel 19 is fixed a small cog-Wheel 33, which rotates with said shaft 11 and meshes with a pinion 34 on a short shaft 35 of the frame 10. Said pinion 34 in turn engages the internal teeth of a large gear-wheel 36, loosely arranged on the shaft 11 at the end of the drum 12 at the end opposite that having the flange 21, but held from longitudinal displacement on said shaft by a collar 37, set upon said shaft 11 by a setscrew or otherwise. The inner side of the internally-toothed wheel. 36 is provided with a friction-cone 201, opposed to the frictioncone 20, and this in turn is engaged by the reverse-cone 211 in the flange 212 of the drum member or section 122.

As before intimated, the drum 12 is in two sections 121 122. These are connected at a point about midway between the llanged opposite ends of the drum by a collar 40, the

inner ends of the said drum-sections being threaded and the said collar being provided with right and left hand female screw-threads to engage the same, the said inner ends of the sections being preferably of solid metal, the said sections being preferably castings, and to prevent independence of rotation the said solid ends are held together by dowel-pins 41, Fig. 3. The said dowel-pins, while fitting their holes or recesses in the solid castings, neatly permit of the longitudinal adjustment hereinafter referred to. The said collar 40 is flanged, as at 42, at the center of its outer periphery, the said flange being recessed, as at 43, or made angular to enable a suitable wrench or other implement to be employed when turning the said flange. Upon turning the said collar the sections 121 122 of the drum are either brought toward one another or separated, and thus adjusted to more exactly and properly secure the desired frictional contact of the cones and to take up or make provision for any wear that may result from continued service.

hen the desired adjustment is obtained, the collar is readily seated in its relation to the drum 12 by means of a set-screw 44 or in any other suitable manner.

The connected compound levers 22, by means of which the opposite screw-shafts 23 231 are simultaneously moved longitudinally in the same direction, are shown in Fi gs. 1 and 2 more clearly, in which the said screw-shafts 23 231 are shown to be provided with arms 221, which at their projecting extremities are pivoted, as at 222, to connecting-rods 223, which in turn are pivoted to levers 224, one of which is provided with a handle 225. The said levers 224 extend downward to a shaft 226, which latter extends across the machine, as shown in Fig. 1, the two levers 224 being keyed upon said shaft 226, and thereby compelling the said levers on opposite sides to move simultaneously and together. Thedistances between the pivots or centers of action of the two sets of levers being uniform, the uniformly-threaded screw-shafts are caused to turn uniformly, and thereby the desired uniformity-of longitudinal movement of the screw-shafts is secured on opposite sides or ends of the shaft 11.

By turning the lever 224 by means of the handle 225, and consequently turning the screw-shafts in their threaded brackets, the longitudinal. key-operating shafts 26 261 are operated simultaneously, the one screw-shaft following the other, so that as one screw-shaft key-shaft, andkey press the other-pressureplate, bringing the last said pressure-plate against the end of the drum-section contiguous thereto and forcing the same longitudinally and reversing the frictional contact of the drum to secure the desired reverse rotation. I

By the construction described I secure the reverse movements of the drum 12, and I secure a release of the mast-rope drum from its cones by a positive action and without the employment of springs, and thus avoid the objections incident to the use of said springs.

It will be understood that the mast-rope is attached to opposite ends of the drum 12, so that the rope will wind on saiddrum at one end and unwind at the opposite end.

' 'In connection with the brackets 24 and 241 I employ oil-wells 4:6 and means,-such as a chain 7, for raising the lubricant from the said well to the shafts.

The wheels 19 and 36 on their inner sides are provided with lateral frames 201, in which an annular series of segmental blocks 202, preferably of wood, are seated,said blocks being inclined at the upper inner surface 203, so as to form the cone. Said blocks are held in their places by pins 204 or other suitable means. I

In operating the device constructed in accordance with the foregoing description, the

parts being shown in the relation partly shown in Fig. 4:, by-operating thecompound levers .22 andturning the screw 23 inward against the shaft 26, the latter pressing on the key 27 forces the pressure-plate 31 against the end of-the drum 12, causing said drum to move longitudinally on its shaft 11 into contact with the cone 5201. Simultaneous with this movement the opposite levers 22, the screw 231, shaft 261,'key 271, and plate 311 move away from the drum to permit such longitudinal movement of the drum. A reverse movement of the levers 22 effect a reverse movement of the said parts.

Having thus described the invention, what I claim as new is 1. The improved hoisting-engine, in which 7 is combined with the bed or frame and the hoisting apparatus, a mast-rope drum and drum-shifting means comprising connected compound levers at opposite sides of said frame, and plates stationed atopposite ends of said drum, and means operated simultaneously by said connected levers and adapted to press one of said plates against the drum and release the other of said plates from said drum, substantially as set forth.
